本文就Y向超声波振动修整砂轮问题进行了理论分析和试验研究,进一步验证和补充了文中引用的日本文献。推导出用各种金刚石笔端振动修整时砂轮表面空间轨迹的数学模型,并通过分析和试验得出非方形笔端适于振动修整的结论。在平面磨床上以不同条件下的试验获得振动修整比普通修整提高砂轮寿命两倍多的结果,并用磨削能通量的概念从理论上阐述了寿命提高的机理。到目前为止,振动修整是直接获得横密纵疏砂轮表面唯一可行的新工艺。
In this paper, the theoretical analysis and experimental research on the Y-ultrasonic vibration dressing grinding wheel are carried out, which further verifies and supplements the Japanese literature cited in the article. The mathematical model of the grinding wheel surface space trajectory with various diamond tip vibrations is deduced. The conclusion that the non-square tip is suitable for vibration dressing is obtained through analysis and experiment. In the surface grinder under different conditions to get the vibration trimming than ordinary trimming to improve the service life of wheel more than twice the result, and use the concept of grinding flux theoretically elaborated the mechanism of life improvement. So far, vibration trimming is the only new technology that can directly obtain the surface of the cross-dense vertical grinding wheel.
